ABSTRACT Tsunamis pose a significant threat to coastal communities and infrastructure throughout the world. In many cases horizontal evacuation is not possible due to the potential local source of the tsunami or the number of people to be evacuated. It is essential that existing buildings, or new emergency centers, be evaluated or designed for vertical evacuation. However, there has been a lack of research on the effect of tsunami waves on coastal infrastructure such as buildings, bridges, and harbor facilities. Furthermore, design guidelines are lacking. To overcome this deficiency, this research will develop the methodology and tools for implementation of site specific Performance Based Tsunami Engineering (PBTE) for use in the analysis, evaluation, design and retrofit of coastal structures and facilities. The technical focus of the work is the simulation of fluid-structure interaction, development of structural loading time histories, and the application of these in a non-linear structural analysis to determine the expected performance of the constructed facilities. Significant potential outcomes include: PBTE methodology; refined and validated analysis tools; requirements for tsunami-resistant structural design, including building code compatible guidelines; performance level specifications; significant efforts in outreach and education; and dissemination of the results.

海啸对世界各地的沿海社区和基础设施构成了重大威胁。 在许多情况下，由于海啸的潜在当地来源或需要疏散的人数，横向疏散是不可能的。 对现有建筑物或新的应急中心进行评估或设计以进行垂直疏散是至关重要的。 然而，一直缺乏研究海啸波对沿海基础设施，如建筑物，桥梁和港口设施的影响。 此外，缺乏设计指南。 为了克服这一缺陷，本研究将开发的方法和工具，用于在分析，评估，设计和改造的沿海结构和设施的网站特定的性能为基础的海啸工程（PBTE）的实施。 这项工作的技术重点是模拟流体-结构相互作用，开发结构载荷时间历程，以及在非线性结构分析中应用这些来确定所建造设施的预期性能。 潜在的重大成果包括：海啸后评估方法;完善和验证的分析工具;抗海啸结构设计要求，包括符合建筑规范的准则;性能水平规格;大力开展外联和教育;传播成果。
